Siemens 3VA4135-5ED34-0AA0 Molded Case Circuit Breaker

This molded case circuit breaker has a 35A current rating and three poles for three-phase circuit protection. Select it when the circuit design calls for a 35A breaker, and coordinate that selection with conductor ampacity and load requirements.

The voltage ratings are 240VAC, 480Y/277VAC, 480VAC, 600Y/347VAC and 250VDC. Match the circuit voltage and AC or DC application to the appropriate rating. In the wye ratings, the first value is phase-to-phase voltage and the second is phase-to-neutral voltage.

The interrupting ratings are 35kAIC at 480Y/277VAC and 18kAIC at 600Y/347VAC. Compare the applicable rating with the available fault current at the installation point; the breaker's interrupting rating must meet or exceed that current.

Both the thermal and magnetic trip settings are fixed. The thermal-magnetic LI function provides long-time overload protection and instantaneous short-circuit protection. Choose it when the protection design calls for fixed settings rather than field-adjustable trip thresholds.

The load-side lug accepts conductors from 14 AWG through 8 AWG. Select a conductor within that range while also meeting the circuit's ampacity requirements; terminal acceptance alone does not determine the correct conductor size.

The breaker body measures 5.5 in high, 3.0 in wide and 3.7 in deep. Use these dimensions when planning the physical layout, allowing additional space for conductor routing and termination work.

The operating temperature range is -25C to 70C. Check the temperature at the breaker location during operation when evaluating the installation environment.

HACR means heating, air-conditioning and refrigeration. This rating is relevant when selecting branch-circuit protection for HVAC and refrigeration equipment; coordinate the 35A selection with the equipment's overcurrent-protection requirements.

The breaker carries CE, CSA and UL approvals, with standards including CSA C22.2 No. 5, IEC 60947-2 and UL 489. Use these when checking the project's required certification and circuit-breaker standards.
